Audi is a leading luxury automaker headquartered in Ingolstadt, Germany and is owned by the Volkswagen Group. The origins of Audi go back to before the turn-of-the-century but the actual mark was introduced in 1965. While Audi struggled with safety and quality during the 1980s, they recovered in the late 1990s and began innovating. A specific example of this is the introduction of LED daytime running lights in 2005. In addition, Audi is well known for their transverse engine layout and "Quattro" all-wheel-drive system, with the name being derived from one of their 1980 models. Audi translates to "hear" in Latin. The german word for hear is "horch," which is also the founder’s last name. Audi has conducted crash tests for over 75 years. They would roll the car down a hill in front of spectators to demonstrate the car’s safety.

Audi's most reported problem on RepairPal is associated with faulty torque converters on some Audi A6 models.
